Suspended tight end Andrew Quarless was allowed to suit up on Saturday for Penn State's game against Oregon State after "new information" indicated he was not connected to the marijuana found Tuesday night in the apartment that he and three teammates share, a source told ESPN.
Defensive ends Maurice Evans and Abe Koroma remain suspended while police decide whether to file charges.
University police seized marijuana from an apartment shared by Evans, Koroma, Quarless and cornerback A.J. Wallace, who Paterno said was not involved in the incident and will be allowed to play Saturday against the Beavers.
No charges have been filed and the investigation is ongoing, Lt. Bill Moerschbacher of the Penn State university police wrote in an e-mail to ESPN.com.
Police were called to the apartment Tuesday night after reports of a loud party. They obtained a search warrant and found a small amount of marijuana.
The Philadelphia Inquirer reported that warrant listed only Wallace and Quarless as residents who were present during the search.
Evans, a first-team All-Big Ten selection, and Koroma are starters at defensive end and defensive tackle, respectively.
Quarless, a reserve tight end, was suspended for spring practice following a DUI arrest on March 2.
He was cited for DUI, failing to stop at a red light and buying alcohol as a minor. The judge sentenced him to a 15-month rehabilitation program, according to the court records.
"They're all three good football players, they're not bad kids," coach Joe Paterno said his radio show Thursday. "But you pay for it when you do dumb things. It's something that they'll be living with. I feel sorry for them and I wish I could do something besides saying, 'You're going to sit out this week, 'til I get all the information.' Because I don't have it all."
The suspensions are the latest in a series of off-field problems for Penn State. Paterno dismissed defensive tackles Phil Taylor and Chris Baker earlier this summer for their involvement in off-field incidents.
Penn State also announced cornerback Willie Harriott has been dismissed from the team for an unrelated issue. In November, Harriott, of New Haven, Conn., was arrested for driving under the influence and speeding.
